modified make files so they respond to JDK_MINOR_VERSION

JDK_MINOR_VERSION is automatically set to 7 by the JDK7 build system
and 8 by the JDK8 built system. so we can use it to determine whether
to insert -DTARGET_JDK_VERSION=7 into CFLAGS when compiling thehotspot
tree.

with this modification we can now replace the icedtea7 hotspot hg tree
with the jdk8-aarch64 hotspot hg tree and build an x86 version of
icedtea7. this is a preliminary step to being able to compile an
aarch64 native Java release of JDK7 based on this hybrid tree.

n.b. the setting of -DTARGET_JDK_VERSION=7 was moved from aarch64.make
into vm.make so as to allow testing the x86 build. it ought to stay
there so we can still retest this when we pull in new changes.
